"to be au fait as to the newest modes of being trifling and silly"

"In the course of a second visit she talked with great openness, and Anne's astonishment increased. She could scarcely imagine a more cheerless situation in itself than Mrs. Smith's. She had been very fond of her husband: she had buried him. She had been used to affluence: it was gone. She had no child to connect her with life and happiness again, no relations to assist in the arrangement of perplexed affairs, no health to make all the rest supportable. Her accommodations were limited to a noisy parlour, and a dark bedroom behind, with no possibility of moving from one to the other without assistance, which there was only one servant in the house to afford, and she never quitted the house but to be conveyed into the warm bath. Yet, in spite of all this, Anne had reason to believe that she had moments only of languor and depression to hours of occupation and enjoyment. How could it be? She watched, observed, reflected, and finally determined that this was not a case of fortitude or of resignation only. A submissive spirit might be patient, a strong understanding would supply resolution, but here was something more; here was that elasticity of mind, that disposition to be comforted, that power of turning readily from evil to good, and of finding employment which carried her out of herself, which was from nature alone. It was the choicest gift of Heaven; and Anne viewed her friend as one of those instances in which, by a merciful appointment, it seems designed to counterbalance almost every other want.

There had been a time, Mrs. Smith told her, when her spirits had nearly failed. She could not call herself an invalid now, compared with her state on first reaching Bath. Then she had, indeed, been a pitiable object; for she had caught cold on the journey, and had hardly taken possession of her lodgings before she was again confined to her bed, and suffering under severe and constant pain; and all this among strangers, with the absolute necessity of having a regular nurse, and finances at that moment particularly unfit to meet any extraordinary expense. She had weathered it, however, and could truly say that it had done her good. It had increased her comforts by making her feel herself to be in good hands. She had seen too much of the world to expect sudden or disinterested attachment anywhere, but her illness had proved to her that her landlady had a character to preserve, and would not use her ill; and she had been particularly fortunate in her nurse, as a sister of her landlady, a nurse by profession, and who had always a home in that house when unemployed, chanced to be at liberty just in time to attend her. "And she," said Mrs. Smith, "besides nursing me most admirably, has really proved an invaluable acquaintance. As soon as I could use my hands she taught me to knit, which has been a great amusement; and she put me in the way of making these little thread-cases, pincushions and card-racks, which you always find me so busy about, and which supply me with the means of doing a little good to one or two very poor families in this neighbourhood. She has a large acquaintance, of course professionally, among those who can afford to buy, and she disposes of my merchandise. She always takes the right time for applying. Everybody's heart is open, you know, when they have recently escaped from severe pain, or are recovering the blessing of health, and Nurse Rooke thoroughly understands when to speak. She is a shrewd, intelligent, sensible woman. Hers is a line for seeing human nature; and she has a fund of good sense and observation, which, as a companion, make her infinitely superior to thousands of those who, having only received "the best education in the world," know nothing worth attending to. Call it gossip, if you will, but when Nurse Rooke has half an hour's leisure to bestow on me, she is sure to have something to relate that is entertaining and profitable: something that makes one know one's species better. One likes to hear what is going on, to be au fait as to the newest modes of being trifling and silly. To me, who live so much alone, her conversation, I assure you, is a treat."
